1. A magnetic resonance imaging apparatus comprising: a controller and scan device that executes, by a phase cycling method plural times, a scan for, after the elapse of an idling time during which RF pulses are repeatedly transmitted every time of repetition in such a manner that spins in an imaging area of a subject are respectively brought into an SSFP state in a static magnetic field space, repeatedly transmitting the RF pulses every said time of repetition to the imaging area in which each of the spins is brought into the SSFP state during the idling time, and receiving magnetic resonance signals generated at the imaging area, and that generates images about the imaging area, based on the magnetic resonance signals received by executing the scan plural times,
wherein the scan device changes the angle of the phase of each RF pulse so as to sequentially increase every said time of repetition to a phase-increased angle at the time that the RF pulses are repeatedly transmitted at a scan executed after the idling time, of the scans executed plural times, thereby transmitting the RF pulses repeatedly.
